摘要
针对最近提出的锚杆重力式海上风机基础形式,采用通用有限元分析软件ABAQUS研究了复合加载条件下此新型基础的承载特性。采用Swipe方法与固定位移比法构造了V(竖向)-H(水平)荷载平面的地基破坏包络线,计算结果表明:随着弯矩的增大,包络线会逐渐缩小。
A novel type of offshore wind turbine foundation, which is named gravity foun dation with anchors, has been proposed recently. The bearing capacity of subsoil under this foundation subjected to combined loading was analyzed in this study using three-dimensional finite element simulations. Failure envelope curves of subsoil in the V（vertical）-H（horizontal） load plane were constructed using both Swipe method and fixed displacement ratio method. It was found that as the bending moment increases, the size of failure envelope curves is reduced gradually.
